DASH diet reduced heart failure risk 'by almost half' in people under 75
Sticking to a plant-rich diet that can reduce high blood pressure may also lower the risk of heart failure in people under the age of 75.
This was the conclusion of a study that a team at Wake Forest School of Medicine in Winston-Salem, NC, led to assess the impact of the Dietary Approaches to Stop Hypertension (DASH) eating plan on heart failure.
They report their findings in a paper that now features in the American Journal of Preventive Medicine.
According to figures from the Centers for Disease Control and Prevention (CDC), there are around 5.7 million adults with heart failure in the United States.
The condition arises when the heart continues to beat but cannot pump blood as well as it should.
The result is that organs and tissues do not get the oxygen and nutrients they need to function properly and remain healthy.
"Heart failure is a frequent cause of hospitalization in older adults and is associated with substantial healthcare costs, so identifying modifiable risk factors [for] heart failure is an important public health goal," says lead study author Dr. Claudia L. Campos, an associate professor of general internal medicine at Wake Forest School of Medicine.
DASH eating plan can lower blood pressure
The DASH eating plan is high in fruits, vegetables, and whole grains, as well as beans, nuts, low-fat or fat-free dairy, poultry, fish, and vegetable oils.
It is low in saturated fats, full-fat dairy, fatty and red meats, salt, sugary drinks, sweets, and tropical oils such as those from coconut and palm.
Some previous studies have shown that the DASH diet can lower blood pressure and low-density lipoprotein, or "bad," cholesterol.
The National Institutes of Health (NIH) promote DASH as part of a "heart-healthy lifestyle" that includes exercising, maintaining a healthy weight, not drinking too much alcohol, managing stress, not smoking, and sleeping well.
Although much of it is similar to the Mediterranean diet, DASH differs in that it emphasizes low-fat dairy and completely excludes alcohol.
The new investigation follows another that also reported that a plant-based diet could cut the risk of heart failure. However, that study focused on people who were aged 45, on average, while the new one examined older adults.
The researchers analyzed records from The Multi-Ethnic Study of Atherosclerosis (MESA), which enrolled men and women at six clinics in different universities across the U.S.
